課室大電視螢幕,簡單使用
簡言:
自新冠肺炎持續至今，網上視像教學以「新常態」的一種方試成為現階段的上課模式。為積極配合社會發展多元學習，為復課後提供學生更豐富的數碼學習環境，我校在停課期間展開為各課室更換數碼大電視工程(首階段是五至六年級)。為老師更容易地掌握大電視螢幕的基本操作，提供了示意圖。
操作共分2部份:
- 視訊源的選取。
- 音訊源的選取。
大電視螢幕的視訊源
I. 選取電腦(PC)源

I was curious if you ever thought of changing the page layout of your blog?
Its very well written; I love what youve got to say. But maybe you could a little more in the way of content
so people could connect with it better. Youve got an awful lot of
text for only having one or two images. Maybe you could space it out better? https://WWW.Brunoimoveisaraxa.Com.br/agente/22casino-app17/
